`Patented .lune 10, 1930 UNITED sra'rss SKILES E. TEST, OF INDIANAPOLIS, INDIANA PROCESS OF AND APPARATUS FOR WARNING AND CLEANING FOOLS Application filed August 24:, 1928.` Serial No. 301,891.

This invention relates to a process of and apparatus for warming and cleaning a swimming pool or the like.

, The chief object of this invention is to renl der a pool sanitary and comfortable by the provision of suitable means so that the predetermined flow ofthe water in the pool can be obtained. y

The chief feature of the invention consists 1o in the formation of an auxiliary draining chamber toward which the surface water drains, and another feature of the invention consists in passing the drainage and warm i surface water through a filter and returnino' the same to the pool below the level thereof to insure4 circulation between the Water of different temperatures so as to retain the normal temperatures in the pool.

rlhe full nature of the invention will be understood from the accompanying drawings and the following description and claims: l

In the drawings Fig. 1 is a vertical longitudinal sectional view of the pool with the apparatus diagramznatically associated therewith. Fig. 2 is atop plan view of the ool. p In the drawings 10 indicates the end walls of a pool, l1 the side walls and 12 the bottom, which preferably is inclined slightly or to the desired degree to provide different depths, although the bottom may be of one level.

To maintain a private pool sanitary in an inexpensive manner is the problem solved by this invention. To do so economically, since a private poolis not in constant use, is also a problem solvedby this invention. To economically maintain normal temperatures in Va private pool where the amount of make-up is relatively small and the cost of a heating system is prohibitive, is another problem solved by the present invention.

The outdoor pool preferably is constructed in a pit 13 and it is usually of rectangular 45 outline, as shown, andis laid with its ends transverse tothe usual direction of prevailing-winds, although the same is not necessary. The purpose of this will be set forth hereinafter.

Adjacent each end of the pool is a battle or partition wall 14C which is substantially at the level 15 of the water in the pool, forming a main chamber 16 and an auxiliary chamber 17 across the end of said pool. The bottom of this chamber maybe inclined as at 18 to a 55 pipe or drain 19. The leaves, sticks, scum, dirt and the like collecting upon the surface 15 of the water.l when there is a flow of the surface water over the to of the partition, flow into and be collecter by the auxiliary `6U chamber. The usual drain 19 secures separation. The flow may be caused by a pump QG discharging at 23 into the pool.

Vfhen cyclic operation is desired, all of the dbris, surface scum or the like passes over into the auxiliary chamber 17, the larger particles collecting therein and the remainder passing out through the pipe or drain 19 to the pump 20, which passes the same through a filter 21 and a pipe line 22 to a nozzle or out- 70 let 23 at the opposite end of the tank or pool. This is a T pipe arrangement with progressively increasing orifices for securing substantially uniform sheet discharge across the full width of the pool. Preferably the out 75 let 23 discharges considerably beneath the surface level, for example, from a foot `to two feet therebeneath. The surface water is usually warm either by reason of Contact with warm air or by reason of the sun shining 1il) upon it or both, and this warm surface water is `returned by the aforesaid construction to the tank and at a level so as to insure a suitable depth of `warm water `in the tank. If the discharge were lower or nearer the bot 55 tom, the warm water taken from the top would pass through the col-d water and mix therewith with the result that the tempera ture of the pool would be constant but not comfortable, as itis desirable `to have the temperature of the top two feet of water in the pool warmer than the remainder of the pool, since it is impracticable or uneconomical to heat the entire contents of the pool. 1 Since there will be considerable evaporation and other losses due to splashing and the like, line 2e controlled by valve 25 supplies the make-up necessary to keep the pool filled." l

114 is shown opposite battle 14 and compartment 117 is formed thereby loored similarly as at 118 and includes the drain 119. At the opposite end the discharge 123 is supplied by line 122 and a valve construction 100 having passages 101 and 102 therein is adapted to selectively connect pipe 19 to pump 20 and line 103toline 22 and iilter 21 by line 104 or connect lines 103 and 104L to lines 119 and 122 respectively for reverse `flow it the wind be in a reverse direction. A single combination valve such asdiagrammatically illustrated at '100 can simultaneously reverse the flow. y

The present invention can be operated and filter the entire tank contents, and its operation will automatically remove the surface dirt and Vscum from lthe tank. That dirt which settles out ot the Water and upon ,the bott-0in 12 of the tank may be suitably. removed by using a suction device such as oit' the, vacuum cleaner type and which is com- When it is desired to drain the tanlr the valve 106 in drain 105is opened and the tankv lcontents is wasted.

The invention claimed is:

Y l1. A swinnning pool including a wall at one end a't substantially the level of the pool contents land'phaving a substantially level top and over which the surface contents of the pool drainsrasa surface sheet for clean` ing the y'top ot thepool, a collection chamber adjacent the pool and into which the sheet drainage is discharged, a discharge into the vra chamber of the Vcharacter described, andV the addition of connectionsbetween the disr charges, chambers, filter, and pool for obtainl Yeo pool nearthe opposite end of the pool and arranged to discharge longitudinally lof the pool and substantially across the` full width thereof, .a filter connected t-o the collection chamber, and a pump interposed between the chamber and the pool and connected to' the .filter whereby circulation of only the pool surface contents through the tllter is obtained. f

2. A swimming pool of the character defined by claim 1, characterized byV each end of the pool having a discharge, a wall and ing reverse surfaceliiow drainage.
